کانورتر یا مبدل ترموکوپل MCP9600 نوع K Type یک ماژول مبدل دما با جبران ساز دمای نقطه اتصال است که از 8 نوع ترموکوپل K, J, T, N, S, E, B و R پشتیبانی می کند و به کاربر اجازه می دهد تا رجیسترهای خروجی را برنامه ریزی کند و با توجه به انعطاف پذیری ماژول از آن در کاربردهای دمایی استفاده کرد.
توسط 4 پین به نام های AL1, AL2, AL3 و AL4 و تعریف پیکربندی مناسب می توان 4 خروجی به زون های مختلف سیستم وصل کرد و وضعیت خروجی هر یک را کنترل کرد و از این حالت در سیستم های مجهز به میکروکنترلر باید استفاده کرد.
Description:
The CJMCU-96 is a fully integrated thermocouple electromotive force (EMF) Celsius converter module with cold junction compensation. The CJMCU-96 supports eight types of thermocouples (K, J, T, N, S, E, B, and R) and provides user-programmable registers for added design flexibility for a variety of temperature sensing applications. The registers allow user-selectable settings such as a low-power mode for battery-powered applications, an adjustable digital filter for fast transient temperatures, and four individually programmable temperature alarm outputs that can be used to detect multiple temperature zones.
The temperature alert limits have multiple user-programmable configurations, such as alert polarity as either an active-low or active-high push-pull output, and output function as a Comparator mode (useful for thermostat-type operation) or Interrupt mode for microprocessor-based systems.
In addition, the alerts can detect either a rising or a falling temperature with up to ±225°C hysteresis. This sensor uses an industry standard 2-wire, I2C compatible serial interface and supports up to eight devices per bus by setting the device address using the ADDR pin.
